.Patented Feb. 17, v1914.

Application filed January 9, 1311. Serial No. 601,693.

To. all whore it may; concern Be it known that I, Jox-IN KLAEHN, of Berlin, in the Province ofOntario, Dominion of Canada, have invented certain new and useful Improvements in Vulcanizing Apparatus; and I do hereby declare that canized for the purpose of securing uniformA vulcanization. For full comprehension, however of my invention, reference must he had to the accompanying drawings forming .a part of this specification, in which similar reference. characters indicate the vsame parts, and 'wherein Figure 1', isv a diagrammatical horizontal' sectional view of a pair of vulcanizing chambers containing my invention; Fig. 2

l is a transverse vertical sectional View taken -tation of the drui in line A, A, Fig. 1 and with a portion of the adjacent wall broken away; and Fig. -3 '1s a longitudinal sectional view illustrating particularly the detail construction of my improved carrier and heating appliance, onev end only thereof bein shown.

The vulcanizing c amber is preferably shaft which also has a pair of miter gears 25 fixed rigidly thereto and driven hy any suitable means, indicated at 5, andpreferably including a re luction gear to secure ro- Js at a low speed.

Each drum has an annular series or' stickcarriers 6, revolubly mounted thereon, and

encircling an electric heater 7 secured rigidly v upon the shaft which is made hollow at hoth ends of each oven, the wires 8 and 9 ofthe' .supply indicated at 53.

heating circuit Abeing taken to the heater, through the interior of the hollow ends of the shaft. Two pairs of commutatore with brushes 5l and 52 are mounted on the shaft at'each end of the chamber and are fed from any available source of electric 1() and 12 indicate rheostats for-controllingV the flow of the heating. currentto regulate the temperature withinthe' ovens.

The stick carriers are made to maintain the sticks carried thereby and the lasts mounted on the sticks constantly in horizontal or level position by pulleys 14:` mounted rigidly upon the` latter, a pulley 15 mounted rigidly upon the'wall of the oven, a pulley 16 mounted rotatably on the frame of the drum, and an endless belt 17 looped around all the said pulleys. i The sticks, indicated at 20 are mounted in 'notched racks 21 fixed upon the carriers 6;

'the sticks and notched racks, per se, bein 75 well known to those .skilled in the arto manufacturing rubber shoes Vand the. like, are not descri ed in detail; l l

Operation: The' sticks having vthe lasted shoes mounted thereonare setinplace in the notched .racks on the lcarriers 6, k'and -when the apparatus is started the belt .17

will drag on 'the fixed pulley 15 and hold the pulleys 14, and, consequently, the stick carriers against' rotation on their axes, thus maintaining the latter with the rows of sticks constantly in the same horizontal plane. The edect is that as the drumrotates and the sticht carriers revolve with it the diiierent points in the circumference of each carrier will he successivedly resented to the heater, and much more uni orm vulcanization secured, owing to the central location of the heater, than has been possible heretofore. 4

Vffhat l claim is as follows z- Y 1. Ina vulcanizing apparatus the combi- `nation with a heater, an annular series of stick carriers encircling the heater and core sisting of carrier members proper and means for attaching the sticks thereto; means for causing the series to revolve; and means acting upon thecarriers for maintaining the same in level position during revolution.
